Ok, I found gcc 4.4.3 on gcc200 and it still produces wrong code:
$ /opt/cfarm/release/4.4.3/bin/gcc -v
Using built-in specs.
Target: sparc64-unknown-linux-gnu
Configured with: ../gcc-4.4.3/configure --prefix=/opt/cfarm/release/4.4.3
--disable-werror --enable-languages=c,c++,fortran,ada --enable-__cxa_atexit
--disable-nls --enable-threads=posix --with-gmp=/opt/cfarm/gmp-4.2.4
--with-mpfr=/opt/cfarm/mpfr-2.4.2 --with-cpu=v8 --disable-multilib
Thread model: posix
gcc version 4.4.3 (GCC)

$ /opt/cfarm/release/4.4.3/bin/gcc -O2 -fPIC hh.c
$ ./a.out
Aborted

It seems to be a problem only when creating 32-bit code, -m64 works fine:
$ /opt/cfarm/release/4.4.3-64/bin/gcc -O2 -fPIC -m64 hh.c
$./a.out
And -m32 aborts of course:
$ /opt/cfarm/release/4.4.3-64/bin/gcc -O2 -fPIC -m32 hh.c
$./a.out

/opt/cfarm/release/4.4.3-64/bin/gcc -v
